| 摘 要： | 本文采用热线风速仪单丝测试技术详细测量了沿流向的单涡、双涡、三涡作用下的涡流场;分析了流向涡在平板湍流边界层内及附近沿程的发展规律以及涡与涡、涡与边界层的相互作用,讨论了流向涡在边界层内部时,用高斯涡核模型假设的适用范围。

| Abstract: | A detailed measurement of the flowfield under the influenceof the vortices has been carried out using the single hot-wire anemome-ter.Analysis is made for the rules of development of streamwise vorticesin the turbulent boundary layer of a flat plate,with interaction betweenvortices,and interaction between vortices and boundary layer considered.Limitations to the assumption of Gaussian vortex model are studied. |
